General Motors Canada (NYSE: GM) said today that it is investing C$691 million in its St. Catharines Propulsion Plant to support production of the sixth generation of General Motors’ V8 engine, which will power GM full-size trucks and SUVs. Yesterday, GM reported strong sales and earnings for Q1 2026 bolstered in part by sales of such vehicles. Complicating GM’s global strategy is the Trump mis-administration’s repudiation of the successful North American Free Trade Agreement (NAFTA) and its subsequent revision proposed, promoted and signed by President Trump known in the U.S. as USMCA (United States-Mexico-Canada Agreement)

“Today’s announcement confirms St. Catharines will play a key role in one of our core vehicle programs for years to come, and it reflects General Motors’ confidence in the St. Catharines team and their proud 74-year legacy of powering our most popular vehicles,” said Jack Uppal, president and managing director, GM Canada.

This investment makes St. Catharines the third GM propulsion plant to produce this new generation of engines alongside Tonawanda Propulsion Plant in Buffalo, New York, and Flint Engine Operations in Flint, Michigan. An integrated propulsion manufacturing footprint will help GM to meet customer demand for high-volume full-size pick-ups in North America.
